Reed is an extensive distributive aquatic plant. There are eight species in China. Pragmites karka (Retz.) is dominant species in Xinjiang, which forms differentially different ecotypes during a long period of time adopting arid environment, aquatic reeds (namely big reed or aquatic reed), salinized-meadow reeds (namely small reed and salt reed) and dune reeds (dune or media reed) and transitional reeds from water to land. Reed is not only a world extensive distributive aquatic plant, but also a regenerative biological resource, and posses economic, social, ecologic value. There are rich resources of reed in Xinjiang, in some places near water source the highest reed reaches 3～5m. In where no surface water, but ground-water level is as deep as 2～5m, transitional reeds are 1～2.5m high, and 1.5～2m at dune. The salinized-meadow reeds grow up to 0.2～1m in height, in where the soil is so sever salinized that salt layers reach 1～5cm on the surface of the soil. Tamrix is the other plant, which can survive in the places of which reeds are found. Utilizing the resource and making it functionality can not only drive Xinjiang economic development, but also boost stockbreeding and provide a new thought for adjusting industrial structure, meanwhile, facilitate fragile ecologic environmental construct and ecologic renewing in Xinjiang.
